摘要： Colored magnetic particles for magnetophoretic display capable of substantially preventing peeling of a pigment therefrom, to thereby prevent contamination of a dispersion medium during use of a magnetophoretic display panel, and a method for manufacturing the same. The colored magnetic particles include magnetic particle elements and a coloring layer formed on each of the magnetic particle elements from a first dispersion liquid using a coating apparatus of a tumbling, fluidizing and granulating type, to thereby color each of the magnetic particles. The first dispersion liquid is constituted of a coloring pigment, synthetic resin and water. The synthetic resin is in the form of an aqueous emulsion. The colored magnetic particles each include a protective layer formed on the coloring layer. The protective layer is formed from a second dispersion liquid constituted of synthetic resin dispersed in water.

摘要： In a surface acoustic wave apparatus, a surface acoustic wave element for obtaining a convolution signal is housed in a recess of a substrate. Since the surface acoustic wave element is housed in the recess of the substrate in this surface acoustic wave apparatus, the apparatus can be compactified. This effect of compactification is remarkable, because the surface acoustic wave element has an output electrode for obtaining the convolution signal and thus originally has a big element size. When a laminate substrate is used as the substrate, a configuration for effectively using surfaces of respective layers may be arranged in such a manner that output wiring of the convolution signal is separately formed in the layers. This further enhances the effect of compactification. There are further disclosed a spread spectrum signal receiver using the above surface acoustic wave apparatus for receiving a spread spectrum signal, and a spread spectrum communication system using the spread spectrum signal receiver.
